Definición de pelvis en inglés:

sustantivo (plural pelvises or pelves-vēz)

He lived only ten weeks after his diagnosis, the disease having already metastasized to his spine and bony pelvis, femur, skull, and tibia.

Since the two iliac bones are bound strongly together at the centre front, the bony pelvis (sacrum and iliac bones) can only be tilted as a whole by movement at the hip joints and by bending the spine.

Laterally, anteriorly and posteriorly the pelvis is bony and significant support is provided through ligaments.
